Application led September 29, 1905. Serial No. 280,659,

Be it known that l, JOHN H. Goss, a citi- Zen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new 4and useful Improvement in Powder -Can To s, of which the following is a full, clear, an eact description.

This invention relates to that class of cans or receptacles which have a fixed top provided with an orifice and a movable device for opening and closing the said orifice and designed to contain a powder to be discharged through Vthe orifice in limited quantities as desired, and a familiar illustration of the lass of devices referred tois the dental or tooth powder can made of metal.

The object of the invention is to stiften the movable device7 permit the flattening of the top, iand render the whole more nearly dustproo The invention consists of a powder-can top having a segmental orifice in its dome and a stop adjacent thereto and a rotatable cover applied to the dome and having a complemental orifice spanned by a bridge adapt ed to ride over the stop as the can is opened and closed, all as i will proceed now more particularly to set forth and finally' claim.

In 'the accompanying drawings, illustrating the invention, in the several figures ci' which like parts are similarly designated, Figure 1 is a top plan view, orifice closed. Fi 2 is a similar view, orifice opened. Fig. 3 1s a top plan view with the parts in position where the bridge and stop are in alincment. Fig. 4 is a vertical cross-section taken in the plane of line A B, Fig. 25. Fig. 5 is a perspcctive view, orifice opened.

The breast 1 supports a cylinder 2, having of this orifice is struck u a lug 5. A bead 6 circumscribes the base oi the dome, and over the dome and around this bead is placed the cover 7, having a milled periphery S, as seen. in Fig'. 5, so as to aicrd a grasping-surface for the thumb and finger in rotating the cover round the cylinder. The cover has an opening 9, corresponding to the orifice 4, but enough longer to include the lug 5,'and this openinglinthe cover spanned by a bridge 10, curved upwardiy, so as to ride over the lug when the cover is rotated around the cyl-` inder to open and close the orifice in the cylinder. When the radial edges of the coveropening come into contact with the lug 5, the further movement of said cover is arrested, and hence the lug constitutes a stop and is herein so referred toA The bridge serves to stiien the cover, permits the fiattening oll the top, and holds the two parts in such intimate contact as to make the top when closed practically dustproof. E

The invention is susceptible of variations in the structurel of the bridge and openings and in the assembling oi the parts.

A powdcr-can top, having a dome provided with a discharge-orifice and an adjacent stop, and a rotatable cover applied to said dome and having a complemental `orifice and a bridge spanning said orifice and adapted to ride over said stop the cover is rotated to cover and uncover the oriiice in the dome.

ln testimony whereof l have hereunto sot my hand this 25th day oi September, A.. l). .1905.
